Poly(aryl piperidinium) Anion Exchange Membrane,20 microns,Self-Supporting

Catalog Number	ACMA00062932
Description	The self-supporting AEMs are manufactured solely from the functionalized poly(aryl piperidinium) resin material and there is no mechanical reinforcement in them. Having the entire membrane manufactured from 100% resin material makes this membrane category to have higher ionic conductivity compared to mechanically reinforced AEM counterparts.
Electrical Conductivity	~150 (mS/cm, OH-, 80 °C)
Elongation At Break	> 20 %
Notice For Use	For standard alkaline fuel cell / electrolysis applications: Allow the membrane to sit at ambient conditions for 1 hr without a cover sheet before use. To convert the membrane to OH- form, place the membrane in an aqueous solution of 0.5 M NaOH or KOH for 1 h at room temperature. After 1 h, replace the solution with fresh 0.5 M NaOH or KOH and allow the membrane to soak for 1 h at room temperature again. After the two soaks, rinse the membrane with DI water (pH ~ 7). Minimize exposure to ambient air, as the CO2 can exchange back into the membrane causing the membrane to convert back to bicarbonate form. The reaction between CO2 and hydroxide ions is purely chemical and it will readily happen if the OH- form of the membrane is exposed to an environment that has CO2 (such as ambient air, etc.). This conversion can be completely eliminated by simply doing the conversion and testing in a CO2-free drybox environment.
